Hi All!
I'm having a problem passing strings into a boost tokenizer. I have been able to get the code to work but I don't think I should have had to do what I did. I don't know if it is tokenizer problem or a compiler problem or my problem.
Basically, I start with a char[] and depending on how I convert it to an std::string, I may or may not get garbage tokens.
I've attached a complete, but small, program to demonstrate the problem. I hope someone can tell what is going on.
I'm using a Fedora 8 system with g++ v 4.1.2.
Thanks in advance!
